COIN-FREEING MECHANISM Eon AUTOMATIC VENDING ND OTHER- MACHINEs;

To all whom it may concern.-

Be it known that I, NORMAN SINCLAIR Mo- NAB, a subject of the King of Great Britain,

residing at Waiora Road, CaulJfield, in the State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in Coin-Freeing Mechanism for Automatic Vending and other Machines, of which the following is a specification.

This invention consists of improvements 1n coin freeing mechanism for automatic vending machines, and the principal object is to insure the ejection of coins of wrong size and weight and to prevent the manually 5 or power operated lever of the machine from being operated until a proper coin is fed into the machine.

The improvements shown in the drawings I p are applied to a stamp vending machineby way of exemplific'ation.

Figure 1 is a sectional plan of a manually operated stamp vending machine with the improvements attached. Figs. 2 and 3 are respectively a vertical section on lines 11-11 and 111111 of Fig. 1. Figs. 4 and 5 are enlarged details of parts shown in Figs. 1-3. Fig. 6 is a sectional view corre sponding to the lower parts of Figs. 2 and 3 illustrating a power means of operating the machine automatically.

Referring to Figs. 15 the coin C'is inserted at slot (1) formed in the casing C and as it abuts against curved shoulder 2 inside said casing it turns by gravity on the ridge 30f plate 3 until it reaches a .sliding angle when it moves or slides under plate 4 on to the receiving tray or plate 5 of'a spring or weight balanced lever 6,

which, if the coin is heavier than the weight the balance is adjusted for, moves and the coin slides off the tray into chufer7 through opening 8 and from thence into the delivery mouth 9 of the machine. The plate 4 prevents the coin from passing over the balancetray 5 until it ceases rocking thereon.

If the coin is lighter than the weight balance lever 6 is adjusted for, the coin slides over same on to plate 10 which is tilted or obliquely arranged forwardly and laterally inclined as shown in Fig. 4. This plate 10 is provided with slot 11 and a projection or ridge 10 on its lower side whereby coins of a. less diametz? n the proper size fall through the sl own the chute 7 and from 65 thence to the delivery mouth or receptacle 9 of the machine.

Specification of Letters Patent.

stamp then drops through tube 41 into the Patented A r. 11, 1916.

Application filed June 17, 1914. Serial No. 845,721.

-A coin passing over the slot 11 moves by gravity against the ridge on the lower side and is, delivered onto a plate or receiving tray 12 of a spring balanced lever 13 the upward movement ofwhich is controlled by a stop 13*. The tray 12 is pivotally' balanced as at 11 upon the spring controlled plvoted lever 13 and 'the movement of the tray is regulated by stops 15,16 thereon.

-The weight of the coin causes" the tray,

which is normally, almost horizontal, to tilt sufliciently to allow the coin to slide off and,

should the coin be lighter than the weight the balance lever 13 is adjusted for, the'coin slides on to plate 17 ofthe chute 7 and-from thence to the delivery mouth 9 of the machine. The tray 12 also has a curved pocket 18 to reduce the rocking or vibration of the coin. If the coin is of the required weightJE-r it moves the balance lever 13 and thecoin slides ofl into the tube 19 and dropping on to arm or plate 20 of lever 30 it moves same to disengage the spring controlled hook or pawl 21 from coin tray 22 on lever 23 by means of projection 30.

The hook 21 and arm 20 above described are pivoted on a common fulcrum 30 so as to permit the hook moving independently'of the arm in the action of the resetting of '85 coin tray 22. The hook is controlled by spring 21 and the arm 20 suitably counterbalanced.

.crank disk 27 connected indirectly with the main operating lever 31 of the vending machine to be turned by lmob 28 to actuate the 7 mechanism ofsaid machine. The knob 28 is not connected rigidly to the crank disk but rotates same through theagency of friction plates 32, 33 and spring 34 as in Fig. 5.

The crank disk has ratchet teeth 35 around its periphery and is prevented from back- I ward rotation by staggered p'awls 36, 37 en-,

gaging therein. The crank disk 27 reciprocates a rod 38 connected to a slide rod 39 which in turn actuates the aforementioned stamp mechanism operating lever 31 by/ link 40. The reciprocating movement ofthis stamp mechanism operating lever feeds the stamp S forward and detaches same and the delivery mouth of the machine.

A grooved knife edge 42 is formed on plate to'cut any threads which maybe attached to coins for the purpose of tamper ing with the machine.

To insure that the coin tray 22 is reset I after each operation, a chain 43 or other suitable telescopic joint is connected between the balance lever 23 and the stamp mechanism operating lever 31 in a'way'that the movement of "the main stamp 'mechanism lever 31 will reset the coin tray lever 22 in engagement with hook 21 before it detaches the stamp just purchased.- i j The empty' dial E (Figs. 2 and; 3) is connected to a balanced lever pivoted as at 44 and held out of sightvby. pin 45* lying normally under and against the stamp band S which passes under a curved plate attached to frame so that when the end of the band clears the edge of plate 50 the lever 45 moves by gravity, as indicated by arrow, and the dial E marked Empty appears at the aperture 46 in front of the machine as in Fig. 2. At the same time a projection 47 on the lever 4:5 is moved into the plane of movement of tray 12 (Fig. 2) which is thus prevented fromv lowering thelever 13 as in- K 17 and from thence to the delivery mouth 9- dicated by dotted lines; so that any. coins now delivered onto tray 12 fall on to plate of the machine.

Instead of a manually turned knob 28 to rotatethe crank disk 27 and so reciprocate the main operating lever 31 of the vending machine said lever 31 may be reciprocated by a crank disk 51 through rod 65 (Fig. 6).

The disk is rotated by a worm52 0n the spindle 62 of anelectro-motor 53 the circuit controlled arm 55 projecting from fulcrum 56 of the coin tray lever 23 and a vessel 57 containing mercury or other suitable contact. A projection 64 on the arm 55 is adapted to engage a spring controlled pawl 63 to hold down the spring controlled contact 54 and maintain the circuit whilethe mechanism ism-operation. Stud 59cm thecrank disk 51 engages projection 60 on tray lever 23. and moving same resets the latter;

the stud also moves the pawl 63v and reerably to the motor spindle'62 so that the. machine may be operatedmanually as well 1 when the machine is unlocked.

1. In coin freeing mechanism for. auto.-

said. lever, and an indicator attached to said second lever.

2. In an automatic vendingorv other machine, of aspring controlled lever, a coin receiving tray mounted on said lever and movable independently thereof for ejecting a coin of insufiicientweight from the ma chine, said lever being movable with said tray to deposit a coin within the machine when a coin of sufiicient weight is received on the tray, and means to prevent the actua tion of said lever.

3. In a coin-freeing mechanism for automatic vending and other machines, a springcontrolled lever, a coin-receiving tray pivotally balanced on said lever, and means movable into'the plane of movement of said tray when the machine is empty and to prevent said spring-controlled lever from being actuated when a coin is received on said tray.

4.. In an automatic vending mechanism a spring-controlled lever, a coin-receiving tray mounted'on said lever and tiltable independently of the latter to eject a coin of insufficient weight from the machine, said lever being actuated with said tray when a coin of proper weight is received by the A latter to deposit said coin in the machine, and means operative when the machine is empty to prevent the actuation of said lever. of which is made by a contact 54: on a spring 1 5. In combination with a vending mechanism and coin-controlled locking means therefor,"v of a' springcontrolled lever, a coin-receiving tray mounted on said lever and tiltable independently of the latter to eject a coinpof insufficient weight, said lever being actuated with said tray when a coin of-fiprop'er-w eight is received by said tray to deliver said coin to said locking means to unlock the latter, and a second lever movable into the path of said tray when the machine is empty to prevent movement of saidfirst-named lever.
